This exhibition at the National Gallery was captivating.
It took each colour in turn with a room dedicated to each.
The sources of pigments used for paint included rocks ,insects and plants.
Examples are art work showing striking use of each colour were shown.
I loved the room showing silver and gold.
It made me want to rush home and have a go myself.
Colour vision depends on the brain.
A film showed how the perception of colour varies according to different light sources.
The exhibition inspired and invited viewers to have a go themselves.
This is just as it should be.
